Brewing Chamber Forced-Air Heating for Stable Beverage Temperature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage machines face challenges in maintaining the brewing chamber and dispensing units at optimal temperature, especially after a period of disuse, leading to suboptimal beverage quality due to temperature fluctuations, and require costly and complex heating systems that often necessitate metal brewing chambers.
Innovation Solution
A forced air temperature regulation system using a fan, heater, and directional duct to maintain the brewing and dispensing units at a predetermined temperature, allowing for precise control and efficient heating without direct contact with the brewing chamber, suitable for use with plastic chambers and reducing energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If heating systems employ circulation of hot water from boiler or heat exchanger, then brewing chamber temperature can be maintained, but device complexity and production cost increase
Solution Approach 1:
The invention extracts the heating function from the complex water circulation/heat exchanger system and implements it through a simpler electric heating element directly integrated into the brewing chamber, eliminating the need for separate heating circuits and reducing overall system complexity
Solution Approach 2:
The heating element is merged directly with the brewing chamber structure, combining the heating function with the chamber itself rather than using separate external heating systems, thereby simplifying the overall device architecture
2Temperature
If electric heating elements are used in contact with brewing chamber, then temperature control is improved, but brewing chamber material is restricted to metal
Solution Approach 1:
The patent introduces a temperature-regulating mechanism that acts as an intermediary between the heating element and the brewing chamber, enabling precise temperature control while being compatible with various materials including plastic, thereby resolving the material restriction issue
Solution Approach 2:
The invention changes the operating parameters of the heating system to allow safe operation with plastic materials, specifically by controlling the heating element temperature and duty cycle to prevent excessive heat transfer that would melt or deform plastic chambers
3Stability of the object's composition
If complex heating systems are used, then temperature stability is improved, but production cost increases
Solution Approach 1:
The patent employs a simple, inexpensive electric heating element that can be easily manufactured and replaced if needed, achieving temperature stability through a low-cost component rather than expensive complex heating systems
Solution Approach 2:
The heating system is designed to be self-regulating with integrated temperature sensing and control, eliminating the need for complex external control systems and reducing production costs while maintaining temperature stability
